026  * <p>An <b>opaque</b> class representing JavaScript client-side objects of the global 
027  * {@link JsClient#HTMLResetElement} class.</p>
028  * <p>This class represents a push button 
029  * in an HTML page, or a {@link JsHTMLInputElement} object created with the HTML 
030  * <tt>&lt;input&gt;</tt> tag with its <tt>type</tt> 
031  * attribute of the value "reset".</p>
032  * <p>An input element of this class is like a push button of {@link JsHTMLButtonElement} 
033  * class created with type "button" but has a more specialized purpose. When a reset 
034  * button element is clicked, the values of all input elements in the {@link JsHTMLInputElement#form} 
035  * that contains it are reset to their default values, specified by the HTML <tt>value</tt> 
036  * attribute or the {@link JsHTMLInputElement#defaultValue} property.</p>
037  * <p>The {@link JsHTMLInputElement#value} property specifies the text to appear in the 
038  * button. A reset button triggers the {@link JsHTMLInputElement#onclick} handler 
039  * before resetting the form, and this handler may cancel the reset by returning <tt>false</tt>. 
040  * For other event cancellation methods see also the {@link JsHTMLFormElement#reset()} 
041  * method and the {@link JsHTMLFormElement#onreset} event handler.</p>
